There are plenty of photos of rockets and space shuttles taking off, but this crystal clear shot of a Delta II rocket is particularly spectacular. Perhaps because you don't know if it's exploding or taking off.
The Delta II rocket was taking the Messenger spacecraft to Mercury from launch pad 17-B at the Cape Canaveral Air Force Station. Obviously, the thing wasn't exploding: The probe is now successfully observing and taking beautiful photographs of Mercury. [Boston.com]
